USB booting :: partitioning

i have a memorex 1G usb drive, i would like to partition it. i partitioned it with cfdisk and it look good it even a sighs the 2nd partition with a mnt/dev but there is an error. so the 1st one is uba1 the 2nd is uba2 i can`t read the 2nd partiton at all.
this is the error i get
"I could not determine the filesystem type, and none was specified"
i have it like this
uba1 type linux
uba2 type fat16

uba1 i can read but it is fat16
uba2 i can not read

HELP?!?!?!?!
